Problems solved by technology

Second, the method cannot distinguish what the contacted object is
That is to say, when any object such as a watch strap or a desktop is close to the sensor, it will be judged as a contact, thereby enabling heart rate measurement, which is obviously unreasonable

Abstract

The invention provides a wearable device for measuring the heart rate, for solving the problem that in the prior art, the measurement for the heart rate is started when that whether an object contacts a device or not can not be accurately judged. The wearable device for measuring the heart rate comprises one or more electrode pairs, or a piezoelectric ceramic plate, wherein a heart rate sensor is triggered to measure the heart rate information through the conduction of the one or more electrode pairs; the heart rate sensor is triggered to measure the heart rate information through current generated by deformation of the piezoelectric ceramic plate. With the wearable device and the heart rate measuring method, whether physical contact exists or not can be accurately judged, the contact between an insulator and the heart rate sensor can be accurately excluded, so that the reliability of measurement for the heart rate is improved, the unnecessary starting of the heart rate sensor is avoided, and the power consumption of the heart rate sensor is reduced.

Description

technical field [0001] The present invention relates to the technical field of sensor power saving, in particular to the field of a wearable device for measuring heart rate and a method for measuring heart rate Background technique [0002] With the improvement of living standards, people begin to pay more attention to the health of themselves and their families. Therefore, wearable devices such as watches and wristbands are becoming more and more popular in the market, because they can monitor many conditions of the human body, such as step counting, sleep monitoring, heart rate monitoring, etc. For heart rate monitoring on wearable devices, measurements are generally made by photovolume scanning. By turning on the green LED (light-emitting diode) light, and then using CMOS (complementary metal oxide semiconductor) to collect the reflected light, and then using a certain algorithm, the heart rate value of the human body can be roughly calculated. [0003] Measuring the he...
